Arthroscopic tarsometatarsal (Lisfranc) arthrodesis

We describe an arthroscopic approach of tarsometatarsal arthrodesis for post-traumatic arthritis. Five tarsometatarsal portals (medial, P1–2, P2–3, P3–4, P4–5) are identified at the junctional points between the metatarsals by means of image intensifier. The first metatarsocuneiform joint is approached through the medial and P1–2 portal. Articular cartilage is denuded and micro-fracture of subchondral bone is performed with an arthroscopic awl. The second metatarsocuneiform joint is approached through the P1–2 and P2–3 portals and the third metatarsocuneiform joint is approached through the P2–3 and P3–4 portals. The articular surfaces are prepared for arthrodesis. The articulations are kept in desired position and transfixed with 4.0 mm cannulated screws. The fourth and fifth metatarsocuboid articulations are rarely included in the procedure. Arthroscopic arthrodesis or tendon arthroplasty of the lateral column can be performed through the P3–4 and P4–5 portals.     

Bilateral complete discoid medial meniscus combined with posterior cyst formation

Bilateral discoid medial menisci is an extremely rare condition of the knee and it can be associated to other pathological findings, including anterior portion cyst formation. We report on the clinical features, radiographic findings, treatment and results of one patient who presented a bilateral medial discoid meniscus combined with posterior portion cyst of the left knee. To the best of the author’s knowledge, this is the first case of bilateral medial discoid meniscus associated with posterior portion cyst formation.

前交叉韧带重建术后骨隧道扩大的产生及转归的MRI随访结果

目的 观察前交叉韧带重建术后骨隧道扩大的发生及随时间的演变。方法 对58例（58膝）接受自体胭绳肌腱移植、挤压螺钉固定的前交叉韧带重建病例进行了2年随访。于术后1、3、6、12和24个月分别进行患肢MRI检查,测量矢状位股骨隧道和胫骨隧道的宽度并与术后1个月数值进行比较,增宽≥2mm为隧道扩大。记录骨隧道扩大出现的时间及不同时间段隧道宽度的改变。结果9膝（15．5％）出现股骨隧道扩大,12膝（20．7％）出现胫骨隧道扩大。2膝术后3个月内出现扩大,16膝3～6个月出现扩大,3膝6～12个月出现扩大。隧道扩大的病例术后1、3个月隧道宽度比较差异无统计学意义（P〉0．05）,术后6、12、24个月隧道宽度大于1、3个月（P〈0．05）,而6、12和24个月之间隧道宽度比较差异无统计学意义（P〉0．05）。结论 前交叉韧带重建术后骨隧道扩大主要出现于术后3～6个月之间,并在术后12～24个月保持稳定。     

关节镜下行(足母)外翻外侧松解背侧入路的研究

目的探讨关节镜下行躅外翻外侧松解背侧入路的可行性及方法。方法解剖研究采用10具新鲜保留踝关节的足部标本。在关节镜监视下,以钩刀松解外侧关节囊和躅内收肌斜头。观察各入路与周围神经血管、肌腱之间的关系,并统计松解范围。临床研究对5例躅外翻患者行关节镜下外侧松解加内侧软组织紧缩手术,患者均为女性,平均年龄30岁。术前躅外翻角为24^o-38^o,平均30^o,跖间角为9^o-11^o,平均10^o。结果解剖研究近侧切口与躅短伸肌腱非常接近,为0—3mm,平均1．5mm;与躅长伸肌腱相距为1—4mm,平均2．4mm。远侧切口与第一趾背动脉和趾背神经非常接近,为1～3mm,平均1、4mm,极易损伤。6例正常足中,1例松解跖籽骨韧带,1例作部分松解（70％）。在4例足母外翻足中,2例松解跖籽骨韧带,1例作了部分松解（50％）。临床研究5例患者平均随访时间9个月。最后一次随访时X线片示足母外翻角4^o-9^o,平均7^o,跖间角8^o～10^o,平均9^o。患者均恢复良好,对外形满意,未见肌腱损伤、麻木、感染、跖趾关节僵硬等并发症发生。结论背侧入路关节镜下外侧松解是可行的,其手术切口较小,镜下视野清晰,可以根据需要松解外侧结构的各个部分,由于不损伤血管,减少了跖骨头坏死的发生。     

关节镜下自体腘绳肌肌腱移植重建膝前交叉韧带的临床观察

目的探讨关节镜下自体腘绳肌肌腱移植重建膝前交叉韧带的临床疗效。方法自2006年12月-2010年1月,对215例膝关节前交叉韧带损伤患者采用关节镜下自体腘绳肌肌腱移植重建（包括单束和双束）。比较患者术前、术后Lysholm膝关节评分和膝关节稳定性改变。结果本组215例中210例获得随访,1例患者在术后6周出现膝关节内感染,予行关节镜下清理、抗感染等处理后治愈。术前和术后1个月、术后6个月、术后1年Lysholm膝关节评分分别比较差异均有统计学意义（P〈0.05）。术前215例患者物理检查均表现为膝关节不稳,术后所有患膝不稳定表现消失。结论关节镜下自体腘绳肌肌腱移植重建膝前交叉韧带疗效可靠,依据病人实际情况个性化合理选择单双束重建。     

Metacarpophalangeal joint arthroscopy: indications revisited

Arthroscopic surgery has become the gold standard for the diagnosis and treatment of major joint disorders. With advancement in arthroscopic technique, arthroscopy has become feasible in most human joints, even those as small as the finger joints. The metacarpophalangeal joint (MCPJ) can become spacious with simple traction, the intra-articular anatomy is simple, and its major structures can be easily visualized and identified. However, MCPJ arthroscopy has never been popular. This article describes our experience with MCPJ arthroscopy and seeks to establish its role in clinical practice.

Abstract：

Objective To evaluate arthroscopy-assisted release of the lateral retinaculum and reefing of the interior retinaculum for treatment of recurrent patello-femoral joint dislocation.Methods From January 2003 to December 2008, 78 cases of recurrent patello-femoral joint dislocation were treated under arthroscopy.They were 23 men and 55 women, with a mean age of 20.3 years (range, 11 to 45 years).Their recurrence of dislocation averaged 5 times.Operative release of the lateral retinaculum and reefing of the interior retinaculum were performed under arthroscopy for all the patients.Auxiliary Goldthwait-Roux procedures were conducted in addition in 13 cases, and auxiliary improved Goldthwait-Roux procedures in 26 cases.We evaluated their subjective symptoms and objective signs, recurrence of patello-femoral joint dislocation, X-ray examinations and functional rehabilitation of the knee joint during the first 3 months, and at 6 and 12 months postoperation.Results Of the 78 cases, 65 were followed up for a mean of 47.3 months (from 19 to 76 months).All the patients were satisfied with the therapeutic effect.Recurrence of dislocation was no longer observed.Seven cases experienced slight pain after excessive motion.The flexion was slightly limited in 5 cases.Six cases reported a sense of patello-femoral malposition.By the Bostman evaluation system, the 65 cases scored 18.5 ±4.5 and 27.5 ±2.5 before and after surgery respectively, showing a statistically significant difference(P=0.018).By the Lysholm evaluation system, they scored 42.3±6.1 and 91.4±4.3 before and after surgery respectively, also showing a statistically significant difference (P = 0.026).Conclusion For treatment of recurrent patello-femoral joint dislocation, arthroscopy-assisted release of the lateral retinaculum and reefing of the interior retinaculum, as well as the auxiliary Goldthwait-Roux or improved Goldthwait-Roux procedures for necessary cases, has the merits of minimal invasion and rapid recovery.
