Preference of surgical procedure for the forefoot deformity in the rheumatoid arthritis patients—A prospective,randomized, internal controlled study

Abstract

Objectives. The deformed rheumatoid forefoot may be treated with resection of lesser metatarsal heads combined with arthrodesis or resection of the first metatarsophalangeal joint. Recurrent hallux valgus deformity has been reported by resection. We performed a prospective, randomized, internal-controlled study to compare results between arthrodesis and resection.

Methods. We resected the lesser metatarsal heads bilaterally and performed arthrodesis of the first metatarsophalangeal joint on one side and resection on the opposite side. We investigated 26 patients (52 feet) who were followed at least one year. Patients were assessed for clinical score, hallux valgus angle (HVA), angle between first and second metatarsals, and angle between first and fifth metatarsals preoperatively, postoperatively and at final follow-up. We evaluated callosities, claw toes, recurrences, and procedure preferences.

Results. The mean follow-up period was 4.1 years. No significant differences between arthrodesis and resection were seen, with the exception of HVA. That was significantly less on arthrodesis side (11.5°) than on resection side (17.0°, p < 0.05). Seven callosities on resection side and four on arthrodesis side were observed. On resection side, hallux valgus deformity often recurred (15.3%). Patients expressed a significant preference for arthrodesis over resection (p = 0.008).

Conclusions. Arthrodesis provides better results for maintaining HVA.     

CC chemokine receptor 5 polymorphism in Italian patients with giant cell arteritis

Abstract

The involvement of valgus hindfoot deformity in hallux valgus deformity was confirmed in a rheumatoid arthritis case with a destructive valgus hindfoot deformity. Correction of severe valgus, calcaneal lateral offset, and pronated foot deformity instantly normalized hallux valgus deformities postoperatively. Thus, careful hindfoot status evaluation is important when assessing forefoot deformity, including hallux valgus, in rheumatoid arthritis cases.     

Anatomy of hallux valgus in rheumatoid arthritis: radiographic analysis using a two-dimensional coordinate system

Abstract

Objective The purpose of this study is to compare the anatomy of rheumatoid hallux valgus with that of idiopathic hallux valgus from the standpoint of joint-preserving surgery.

Methods One hundred forty-eight feet of 81 rheumatoid patients were included. Feet with idiopathic hallux valgus and normal feet were compared as controls. Weight-bearing dorsoplantar radiographs of the feet were taken of each patient. A two-dimensional coordinate system was defined on the radiographic image, and 19 anatomic points of the forefoot were measured.

Results In rheumatoid hallux valgus, the first metatarsal head shifted medially as hallux valgus angle increased, which was similar to the deformity of idiopathic hallux valgus. Proximal deviation of the tips of the lesser toes, caused by clawing and dislocations of the metatarsophalangeal joints, occurred in rheumatoid hallux valgus. Specifically the tips of the second toes in rheumatoid hallux valgus were located more proximally than those in idiopathic hallux valgus irrespective of the severity of hallux valgus.

Conclusions Corrective osteotomy of the first metatarsal is a reasonable procedure for rheumatoid hallux valgus. Additionally, correction of the second toe deformity to make a stable lateral support on the hallux may be another important factor for successful joint-preserving surgery.     

Foot deformities in rheumatoid arthritis and relevance of foot function index

The aim of this study were to assess what type of foot deformities are found in rheumatoid arthritis (RA) patients, to detect frequency of deformities, and to evaluate deformities affecting Foot Function Index (FFI) and patient functional capacity. Anteroposterior and lateral weight-bearing radiographs of 156 feet of 78 patients who had RA for ≥2 years and of 76 feet of 38 healthy controls were studied. We measured hallux valgus angle, intermetatarsal angle between first and second (M1/2) and intermetatarsal angle between first and fifth (M1/5) on anteroposterior radiographs, and calcaneal pitch on the lateral radiographs. We examined the feet of all RA patients and healthy controls for hallux rigidus, cock-up deformity, clawing toe, and mallet finger, and measured calcaneal valgus angle. FFI, comprised of pain, disability, and activity limitation subscales, was administered to all RA patients. Their Steinbrocker Functional Class (SFC) and Health Assessment Questionnaire (HAQ) scores were determined. We determined frequency of deformities as 96.2% in RA patients and 97.4% in controls by radiological and physical examination (p>0.05). The frequency of each deformity was markedly increased in RA patients, with the exception of calcaneal valgus deformity. There was significant correlation between SFC and HAQ with FFI and subscales (respectively, r=0.46, p=0.001; r=0.67, p=0.001). For FFI and subscales, HAQ was the most important predictor factor, followed by gender and hallux rigidus. Foot deformities are seen very frequently in RA. These deformities may affect patient functional foot, especially hallux rigidus and calcaneal valgus.     

Mid-term results of joint-preserving procedures by a modified Mann method for big toe deformities in rheumatoid patients undergoing forefoot surgeries

This study aimed to evaluate joint-preserving procedures by a modified Mann method for rheumatoid forefoot deformities and their functional outcomes in the mid-term. Eleven feet in seven patients underwent forefoot surgery using a modified Mann method for the big toe, combined with offset osteotomy or resection arthroplasty of the lesser toes. The mean follow-up period was 3.6 years. The mean score on the Japanese Society for Surgery of the Foot scale for rheumatoid arthritis foot and ankle joints improved from 44.0 to 72.0. The mean hallux valgus angle improved from 39.4° to 20.5° and the mean M1M5 angle improved from 31.1° to 25.8°. However, deformities involving a hallux valgus angle of more than 25.0° recurred in three feet at the latest follow-up, although the patients did not complain of any symptoms from the recurrence. Improvement in the Sharp score for joint space narrowing was observed in the big toe, indicating better congruity of the metatarsophalangeal joint. For restraint of rheumatoid forefoot deformities, a modified Mann method, combined with offset osteotomy or resection arthroplasty, was satisfactory for not only improving the foot function, but also preserving the metatarsophalangeal joint mobility.     

Comparison between resection arthroplasty alone and resection arthroplasty with arthrodesis of the first MTP joint for rheumatoid forefoot deformities

Abstract

It has been reported that nearly 90% of patients with rheumatoid arthritis (RA) have problems with their feet. Several methods of treating hallux valgus deformity in RA have previously been reported, including arthrodesis and joint resection, and good results have been observed with surgical procedures. In this report, we compare the clinical and radiological outcomes of resection arthroplasty alone (the first method) and resection arthroplasty with arthrodesis of the first MTP joint (the second method) for the treatment of forefoot deformities of RA patients. On clinical assessment, the American Orthopaedic Foot and Ankle Society (AOFAS) scale score significantly improved in both methods; however, the second method gave better results than the first method in relation to the footwear and alignment components. On radiographic assessment, in the first method there were no significant changes in the valgus angle (H–V angle) and the fifth metatarsal bone (M1/5) angle between preoperation and last follow-up. In contrast, these angles were decreased in the second method. One of the most important issues in the treatment of forefoot deformities in RA patients is to correct splaying foot deformity. We believe that the second method, which can correct splaying foot deformity, is currently the most reliable treatment method.     

A modified Hohmann method for hallux valgus and telescoping osteotomy for lesser toe deformities in patients with rheumatoid arthritis

To preserve the function of metatarsophalangeal joints and to ensure forefoot stability in patients with rheumatoid arthritis (RA), we performed a modified Hohmann method for hallux valgus (HV) and telescoping osteotomy of lesser toe deformities instead of fusion of HV or resection of all metatarsal heads. From October 1995 through March 2001, 47 RA patients (90 feet) with severe HV and forefoot deformities were examined. The indication for the procedure in all the patients was disabling foot pain secondary to intractable plantar callosities below the lesser metatarsal heads, painful HV deformities, and the severe deviation of the sesamoid complex diagnosed by the basis of X-ray images. The HV and intermetatarsal (M1M2 and M1M5) angles and sesamoid complex were measured on the preoperative and postoperative roentgenograms. According to the results of a questionnaire survey, the patients were divided into three groups using the visual analogue scale; group 1: satisfied, group 2: fair and or no pain, group 3: dissatisfied. HV and M1M2 angles significantly improved compared between pre- and postoperative or preoperative and the follow-up periods. Out of the 47 patients, 78.9% were satisfied with the results of the operation and 8.9% were dissatisfied. Of these patients, 12.2% reported fair results. There were several complications, such as painful callosity, which was recurrent in seven feet, and delayed wound healing was observed in two out of 90 feet. A modified Hohmann method and abductor hallucis correction are effective in relieving pain and ensuring the bony union of the great toe in spite of severe osteoporosis.     

A modified Hohmann method for hallux valgus and telescoping osteotomy for lesser toe deformities in patients with rheumatoid arthritis

To preserve the function of metatarsophalangeal joints and to ensure forefoot stability in patients with rheumatoid arthritis (RA), we performed a modified Hohmann method for hallux valgus (HV) and telescoping osteotomy or shortening of lesser toe deformities. Forty-seven RA patients (90 feet) with severe HV and forefoot deformities were examined. The indication for the procedure in all the patients was disabling foot pain secondary to intractable plantar callosities below the lesser metatarsal heads and painful HV deformities. The HV and intermetatarsal (M₁M₂) angles and sesamoid complex were measured on the preoperative and postoperative roentgenograms. Visual analogue scales were studied preoperatively, postoperatively, and in the follow-up period. HV and M₁M₂ angles significantly improved compared between the pre- and postoperative conditions. Out of the 47 patients, 78.9% were satisfied with the results of the operation, 8.9% were unsatisfied, and 12.2% reported fair results. There were several complications, such as painful callosity, which was recurrent in seven feet, and delayed wound healing was observed in two out of the 90 feet. A modified Hohmann method and abductor hallucis muscle correction are effective in relieving pain and ensuring the bony union of the great toe in spite of severe osteoporosis.     

Use of grommet for Swanson flexible hinge toe implant arthroplasty for hallux valgus deformity of rheumatoid arthritis]

OBJECTIVES: We reviewed the results of arthroplasty of the great toe with hallux valgus in rheumatoid patients, using a Swanson flexible hinge toe implant protected by grommet. MATERIALS AND METHODS: Sixteen patients (26 feet) with rheumatoid arthritis were operated on from 1996 to 1999. (fifteen women, one man). The average age was 59.8 years (range, 48-73 years). The average follow-up period was 3.0 years (range, 1.0-4.5 years). In each patient, the hallux valgus angle (HVA) was measured before and after surgery, and implant breakage and radiolucency around the implant were evaluated on radiographs. RESULTS: Average HVA was 47.7 degrees preoperatively and 19.3 degrees postoperatively. No implant breakage was observed in 76.9% of the feet. Radiolucency of more than 2 mm was observed in only 3.8% of the feet. CONCLUSIONS: These findings suggest that arthroplasty using a Swanson flexible hinge toe implant with a grommet is useful for treatment of hallux valgus in rheumatoid patients.     

Outcomes of modified metatarsal shortening offset osteotomy for forefoot deformity in patients with rheumatoid arthritis: Short to mid-term follow-up

Objectives: Advances in drug therapy for rheumatoid arthritis (RA) have been encouraging us to preserve the metatarsopharangeal (MTP) joint in correction of forefoot deformities, and original metatarsal shortening offset osteotomy was recommended as one of the conventional surgical options for forefoot deformities in RA cases. The objective of this study was to evaluate short- to mid-term outcomes of modified metatarsal shortening offset osteotomy.

Methods: A retrospective observational study was completed for 80 RA cases (mean follow-up period: 3.2 years) who underwent modified metatarsal shortening offset osteotomy. Both lesser toe scales and RA foot ankle scales were administered using the Japanese Society for Surgery of the Foot (JSSF) standard rating system, and a postoperative self-administered foot evaluation questionnaire (SAFE-Q) at final follow-up was also checked to evaluate clinical outcomes.

Results: This procedure significantly improved clinical scores of both the JSSF [lesser toes and RA foot and ankle] scales. Of 80 feet, 24 (30%) showed recurrence of MTP joint subluxation/dislocation. Furthermore, the feet in the recurrence group showed significant varus hindfoot. On the other hand, valgus foot in the recurrence group more frequently included midfoot bony ankyloses. All of the affected feet showed the limitation of MTP joints (<70°) after surgery.

Conclusions: Modified metatarsal shortening offset osteotomy was recommended for RA forefoot disorders as one of the joint preservation surgeries in short- to mid-term follow-up. However, some modifications to avoid limitation of ROM in the MTP joint are required. It must be borne in mind that varus hindfoot and/or bony ankyloses in the mid-hindfoot can cause recurrence of dorsal dislocation/subluxation of the lesser toe MTP joint.     

Proximal rotational closing-wedge osteotomy of the first metatarsal in rheumatoid arthritis: clinical and radiographic evaluation of a continuous series of 35 cases

Objectives

The introduction of powerful antirheumatic drugs has dramatically improved the treatment of rheumatoid arthritis (RA), leading clinicians to reconsider the benefits of joint preservation for rheumatoid forefoot deformities. We have employed joint-preserving forefoot surgeries, including rotational closing-wedge osteotomy of the first metatarsal. The aim of our study is to assess the short-term results of this procedure.

Methods

From January 2011 through December 2011, 35 feet were treated with this procedure. Subjective, functional, and radiographic outcomes were surveyed.

Results

The mean Japanese Society for Surgery of the Foot improved from a preoperative level of 52.6 to 68.7 postoperatively. The average hallux valgus and intermetatarsal angles improved from 47.3° preoperatively to 17.5° postoperatively, and from 16.7° preoperatively to 9.0° postoperatively, respectively. To assess the repositioning of pronation deformities of the first metatarsal, the position of the medial sesamoid was also surveyed according to the measurement system proposed by Hardy and Clapham. All feet except two were classified as grade V or higher preoperatively; 25 of these were grade IV or lower at the latest follow-up.

Conclusions

Rotational closing-wedge osteotomy of the first metatarsal was beneficial for correcting forefoot deformities in RA over the short term.     

Comparison between resection arthroplasty alone and resection arthroplasty with arthrodesis of the first MTP joint for rheumatoid forefoot deformities

It has been reported that nearly 90% of patients with rheumatoid arthritis (RA) have problems with their feet. Several methods of treating hallux valgus deformity in RA have previously been reported, including arthrodesis and joint resection, and good results have been observed with surgical procedures. In this report, we compare the clinical and radiological outcomes of resection arthroplasty alone (the first method) and resection arthroplasty with arthrodesis of the first MTP joint (the second method) for the treatment of forefoot deformities of RA patients. On clinical assessment, the American Orthopaedic Foot and Ankle Society (AOFAS) scale score significantly improved in both methods; however, the second method gave better results than the first method in relation to the footwear and alignment components. On radiographic assessment, in the first method there were no significant changes in the valgus angle (H–V angle) and the fifth metatarsal bone (M1/5) angle between preoperation and last follow-up. In contrast, these angles were decreased in the second method. One of the most important issues in the treatment of forefoot deformities in RA patients is to correct splaying foot deformity. We believe that the second method, which can correct splaying foot deformity, is currently the most reliable treatment method.     

Appearance of hindfoot valgus deformity and recurrence of hallux valgus in the very early period after hallux valgus surgery in a poorly controlled rheumatoid arthritis case: A case report

Abstract

Control of rheumatoid arthritis (RA) disease activity is an important factor related to the development of hallux valgus (HV) deformity. Furthermore, if valgus hindfoot remains and/or appears after HV surgery, the affected foot is at risk of recurrence of HV deformity. We experienced a case suggesting the possibility that hindfoot valgus deformity appeared after HV surgery because of poor control of RA disease activity, and the HV deformity recurred in the very early period after surgery.     

Replacement of the first metatarsophalangeal joint with a Swanson implant accompanied by open-wedge osteotomy of the first metatarsal bone for hallux valgus in rheumatoid arthritis

Hallux valgus is very common in rheumatoid arthritis (RA) and mostly accompanied by varus deformity of the first metatarsal bone, which is often corrected in surgeries for hallux valgus in nonarthritic condition, but rarely in RA. We performed the replacement of the first metatarsophalangeal (MTP) joint with a Swanson hinge toe implant accompanied with open-wedge osteotomy of the first metatarsal bone, aiming at reconstruction of a functioning first MTP joint without recurrence of hallux valgus. Fifteen feet of 11 patients with RA were studied with a mean follow-up period of 45.1 months. The American Orthopaedic Foot and Ankle Society (AOFAS) scale improved significantly from 39 points preoperatively to 81.7 at the last follow-up. The hallux valgus angle (HVA), angle between the first and second metatarsal bones (M1/2), and that between the first and fifth (M1/5), measured on standing anteroposterior radiographs, decreased significantly from 49.8°, 16.7°, and 34.4° preoperatively to 10.9°, 8.7°, and 22.2° at the last follow-up, respectively. Union of the corrected first metatarsal bone was recognized in all cases and no such problems as infection, dislocation, or implant fracture were observed. These data suggest that replacement of the first MTP joint with a Swanson implant accompanied with open-wedge osteotomy of the first metatarsal bone can be a useful option for hallux valgus in RA.     

Long-term outcome of joint-preserving surgery by combination metatarsal osteotomies for shortening for forefoot deformity in patients with rheumatoid arthritis

Abstract

Objectives. We report the long-term outcome of joint-preserving surgery by combining metatarsal osteotomies for shortening for forefoot deformity in patients with rheumatoid arthritis (RA).

Methods. Forty-three patients (57 feet) aged 41.7–70.8 years (mean, 57.7 years) underwent a combination of first tarsometatarsal fusion and distal realignment (modified Lapidus procedure), shortening oblique osteotomies of the bases of metatarsals 2–4, and fifth ray osteotomy (modified Coughlin procedure). Patients were followed up for 64–108 months (mean, 76.6 months).

Results. Average postoperative Foot Function Index scores for pain, disability, and activity were 10.3, 19.9, and 16.2, respectively. Average Japanese Society for Surgery of the Foot RA foot and ankle score improved significantly from 52.1 points preoperatively to 90.3 points postoperatively. Postoperatively, 41% of patients reported some forefoot stiffness, but showed no disability. Residual deformity and callosity were absent in all patients. Average hallux valgus and intermetatarsal angles decreased postoperatively from 48.5° to 8.6° and from 15.2° to 4.6°, respectively. Nonunion in two metatarsals, hardware breakage in three, and mild infection in one were identified during follow-up.

Conclusions. With good perioperative medical management of RA, surgical repositioning of the metatarsophalangeal joints by proximal metatarsal shortening and consequent relaxing of the surrounding soft tissue shows successful long-term results.     

Association between preoperative pain intensity of MTP joint callosities of the lesser toes and fore-mid-hindfoot deformities in rheumatoid arthritis cases

Objectives: To determine whether preoperative pain intensity in callosities of the lesser toe metatarsopharangeal (MTP) joint was associated with the grade of fore-mid-hindfoot deformities, because rheumatoid arthritis (RA) foot deformity includes the whole part of foot, and curiously differences between cases in the pain intensity of MTP joint callosities are often observed.

Methods: We evaluated 24 feet that had undergone forefoot surgery [August, 2014 – December, 2015] for painful lesser toe MTP joint deformity (callosities) in RA cases. A preoperative self-administered foot evaluation questionnaire (SAFE-Q) and pressure distribution information for foot function were also investigated. X-rays of the whole lower extremities and foot at weight-bearing were used to check fore-mid-hindfoot deformities.

Results: Group M (mild) [n?=?9] included patients with the pain visual analog scale (VAS) less than 40?mm, while group S (severe) [n?=?15] included patients whose VAS was over 40?mm. Group M showed stronger hindfoot valgus and pronated (abducted) deformity, and group M showed higher pressure on the first MTP joint compared with group S.

Conclusions: These observations reconfirm that hindfoot valgus deformity and/or pronated (abducted) foot deformity affects the forefoot loading distribution, subsequently the pain of callosities in lesser toe MTP joints could be decreased.     

Plantar pressure and surgical indication of toe arthroplasty for rheumatoid forefoot deformity

Objectives: The objective of this study is to clarify the surgical indication for rheumatoid forefoot deformity according to background characteristics and plantar pressure.

Methods: Patients with rheumatoid arthritis were divided into a non-surgical group (group N) and a surgical group (group S). The former consisted of 225?ft, and the latter consisted of 88?ft. DAS28, Japanese Society for Surgery of the Foot rheumatoid arthritis foot and ankle scale (JSSF scale) and hallux valgus angle (HVA) were evaluated as background characteristics. Distribution of peak pressure as plantar pressure was measured in nine sections.

Results: In groups N and S, the mean DAS28 was 3.6 and 3.0, the mean JSSF scale was 81.1 and 63.0, and the mean HVA was 19.9° and 35.3°, respectively. The mean peak pressure of group S at the first and third metatarsophalangeal joints was significantly higher compared with group N. Significant differences between the two groups were also seen in Δ pressure (the difference between the maximum and minimum peak pressure values). The cut-off values were 75.0 for JSSF scale, 24.9° for HVA and 3.94?kg/cm² for Δ pressure.

Conclusions: The combined assessment of HVA and Δ pressure was found to be useful as an indication for surgical treatment of the forefoot.     

Radiological evaluation of foot deformities in rheumatoid arthritis]

Deformities of the feet are common in patients with rheumatoid arthritis (RA). We investigated whether there was any correlation among forefoot deformities, flat foot or articular destruction of the midfoot and hindfoot, in 146 feet of 73 RA patients whose age varied from 26 to 81 years (mean 58.5 years). In all patients, anteroposterior (AP) and lateral radiographs of the feet with weight bearing were obtained. The hallux valgus angle (HVA), the intermetatarsal angle between the 1st and 2nd metatarsals (M 1 M 2), and the intermetatarsal angle between the 1st and 5th metatarsals (M 1 M 5) were measured on AP radiographs. On slateral radiographs, the height of the arch was measured and articular destruction of the talocalcaneal, talocrural, talonavicular, cuneonavicular and cuneometatarsal joints was measured and classified using Steinbrocker's classification. The average HVA was 23.4 degrees, the average M 1 M 2 was 11.1 degrees, and the average M 1 M 5 was 28.4 degrees. There was no correlation between forefoot deformities and flat foot. There were significant correlations between arthritic destruction of the cuneometatarsal joint and HVA, M 1 M 2 and M 1 M 5. The correlations between arthritic destruction of the cuneonavicular joint and HVA or M 1 M 2 were also significant, although weaker. Thas, we found some relationships between forefoot deformity and arthritics destruction of midfoot joints. Especially, the correlations between arthritic destruction of the cuneonavicular and cuneometatarsal joints and forefoot deformities were significant. Many radiographic methods for the assessment of RA have been reported, however, it is difficult to assess sarthritic destruction of rheumatoid feet with the existing methods. Accordingly, a new method should be established.     

Recurrence of deformity after silicone implant and resection arthroplasty of the metatarsophalangeal joint for rheumatoid arthritis: long-term results

Objective: To examine the recurrence of deformity after silicone implant arthroplasty combined with resection arthroplasty for severe forefoot deformity in patients with rheumatoid arthritis.

Methods: We reviewed the long-term results of this procedure for 27 feet in 15 patients. Their average age and disease duration at the time of operation were 58.6 years and 17.5 years, respectively, and the average follow-up period was 10.3 years.

Results: An improved hallux valgus angle (45.3° preoperatively, 23.6° 6 months after operation) was maintained. By contrast, deformity and dislocation of lesser toe had recurred at the final follow-up; the angle between the proximal phalanx and the metatarsal of the second toe improved 13.4° with recurrence of 22.5°, the angle between the proximal phalanx and ground surface improved 22.4° with recurrence of 34.5. Furthermore, claw toe deformity at the final follow-up was significantly worse in the group whose hallux valgus deformity was observed 6 months after operation.

Conclusion: This procedure could maintain the alignment of the first metatarsophalangeal joint, but the recurrence of claw toe deformity is a problem and the relation between the first toe and the lesser toe is an important consideration.     

Comparison of a self-administered foot evaluation questionnaire (SAFE-Q) between joint-preserving arthroplasty and resection-replacement arthroplasty in forefoot surgery for patients with rheumatoid arthritis

Objectives: To clarify the difference of patient-based outcome between joint-preserving arthroplasty and resection-replacement arthroplasty in forefoot surgery for patients with rheumatoid arthritis (RA).

Methods: A total of 63 feet of 49 RA patients who underwent forefoot surgery were asked to answer pre-operative and post-operative self-administered foot evaluation questionnaire (SAFE-Q). Patients were treated with either (1) metatarsal head resection-replacement arthroplasty (28 feet, post-operative mean age 63.8 years, follow-up 4.2 years, DAS28-CRP 2.2) or (2) metatarsophalangeal joint-preserving arthroplasty (35 feet, post-operative mean age 63.1 years, follow-up 3.6 years, DAS28-CRP 2.1) at each surgeon’s discretion.

Results: Mean pre-operative and post-operative subscale scores of SAFE-Q of group (1) and (2) were as follows. Pain and pain-related [(1) pre-op 36.8 to post-op 75.0 vs. (2) pre-op 42.2 to post-op 82.6], physical functioning and daily-living [(1) 43.2–68.8 vs. (2) 52.778.1], social functioning [(1) 44.3–72.0 vs. (2) 52.5–81.9], general health and well-being [(1) 48.4–68.4 vs. (2) 45.5–84.4], and shoe-related [(1) 30.1–50.3 vs. (2) 30.6–64.4]. Both general health and well-being subscale scores (p?p?Conclusions: Joint-preserving arthroplasty resulted in better patient-based outcomes than resection-replacement arthroplasty.
