内侧半月板Ramp损伤的研究进展

前交叉韧带损伤常合并内侧半月板Ramp损伤,陈旧性前交叉韧带损伤更易合并内侧半月板Ramp损伤。MRI与膝关节镜检查是确诊内侧半月板Ramp损伤的主要方法。内侧半月板Ramp损伤以手术治疗为主,包括关节镜下内侧半月板后角部分切除、单纯撕裂部位的创面新鲜化技术或全内缝合术式。Ramp损伤,近期疗效显著,远期疗效有待进一步观察。本文对国内外近年有关内侧半月板Ramp损伤的相关文献进行综述。

The Results of All-Inside Meniscus Repair Using the Viper Repair System Simultaneously with Anterior Cruciate Ligament Reconstruction

Background

Meniscus tears are commonly associated with anterior cruciate ligament (ACL) ruptures. It is essential to repair meniscal tears as much as possible to prevent early osteoarthritis and to gain additional stability in the knee joint. We evaluated the results of arthroscopic all-inside repair using the Meniscal Viper Repair System (Arthrex) on meniscus tears simultaneously with ACL reconstruction.

Methods

Nineteen out of 22 patients who were treated with arthroscopic all-inside repair using the Meniscal Viper Repair System for meniscus tear associated with ACL rupture were evaluated. ACL reconstructions were performed at the same period. The mean follow-up period was 16.5 months (range, 12 to 24 months). The clinical results of the meniscus repair were evaluated by symptoms (such as catching or locking), tenderness, effusion, range of motion limitation, and the McMurray test. Clinical success was defined by negative results in all five categories. The Hospital for Special Surgery (HSS) score was evaluated. Objective results were evaluated with secondary look arthroscopy or magnetic resonance imaging (MRI). The MRI results were categorized as completely repaired, incompletely repaired, and failure by Henning''s classification. The results of second-look arthroscopy were evaluated with the criteria of meniscal healing.

Results

The clinical success rate was 95.4% and the HSS scores were 93.9 ± 5.4 at the final follow-up. According to Henning''s classification, 15 out of 18 cases showed complete healing (83.3%) and two cases (11.1%) showed incomplete healing. Seventeen out of 18 cases that underwent second-look arthroscopy showed complete healing (94.4%) according to the criteria of meniscal healing. Only one case showed failure and the failure was due to a re-rupture at the sutured area. Complications of ACL reconstruction or meniscus repair were not present.

Conclusions

The results demonstrate that arthroscopic all-inside repair using the Meniscal Viper Repair System is an effective treatment method when it is performed simultaneously with ACL reconstruction.     

Second-look arthroscopy with removal of bioabsorbable tacks

Eleven years after tearing her anterior cruciate ligament (ACL) (not reconstructed), a 36-year-old dancer reinjured her knee and required arthroscopic ACL reconstruction. At arthroscopy, the medial meniscus had a bucket-handle tear that was repaired by using three bioabsorbable tacks. The ACL was then repaired in the usual manner. Because of persistent posterior knee pain throughout her rehabilitation, we performed "second-look" arthroscopy 14 weeks after reconstruction. The meniscus had healed and was stable; however, tack motion was evident and the tacks were easily removed. Inspection of the tacks showed that the barbs had been resorbed. The patient recovered uneventfully, and pain-free flexion 28 days after surgery was 0 degrees-136 degrees. We believe this to be the first reported case demonstrating the early stages of tack degradation in meniscal repair.

目的 探讨关节镜手术治疗前交叉韧带(ACL)合并半月板损伤的方法及疗效.方法 关节镜下对135例ACL合并半月板损伤患者行ACL重建,同时行半月板修复或半月板修整.结果 患者均获随访,时间3～12个月,术后未出现关节粘连、血管神经损伤等并发症,半月板修整患者均无交锁且回旋挤压试验阴性.半月板修复患者3个月时随访,回旋挤压试验阳性1例;12个月时随访,回旋挤压试验阳性3例,交锁1例,两者都有1例.Lysholm评分:手术前为(46.3±6.2)分,术后6个月为(73.4±7.6)分,术后12个月为(87.8±8.2)分,术前与术后比较差异有统计学意义(P<0.01).结论 ACL与半月板常同时损伤,手术前应作好ACL重建及半月板修复或修整准备,关节镜同期治疗ACL并半月板损伤可取得较好疗效.     

Arthroscopic verification of meniscus repair]

The purpose of this study was to verify the arthroscopic meniscus repair by second-look arthroscopy. From November 2001 to October 2005, 28 meniscus (18 medial and 10 lateral) were repaired in 26 patients (two patients had both menisci in one knee repaired). There were 11 females and 15 males. The average age at surgery was 25.5 (range, 13 to 52 years of age). The indication for repair was a full-thickness, vertical tear > or = 8 mm. Meniscus repair was combined with partial meniscectomy of posterior horn because of horizontal tear in 3 cases. In 1 zone 14 meniscus were injured and in 2 zone--also 14 meniscus, according to Cooper's classification. All patients had anterior cruciate ligament rupture. The average time interval between the injury and the repair was 22 weeks (range, 2 weeks to 2 years). The inside-out suture was used in 18 repairs, all inside--3 repairs, outside-in--2 repairs and a mixed technique--5 repairs. Arthroscopic evaluation of meniscus repair was performed on average after 15 weeks (range, 2 months to 37 weeks) since the suture. That was done during the second stage of treatment--ACL reconstruction. There were 78.6% of completely healed repairs, 10.7% of incompletely healed and 10.7% were not healed.     

Suture of new and old peripheral meniscus tears

A prospective study of repaired vertical peripheral tears of the meniscus in fifty patients (nine women and forty-one men) was carried out from January 1977 to June 1980. All tears were confirmed preoperatively by arthroscopy. Forty-three medial and seven lateral menisci were repaired. Fifteen tears were treated within two weeks and thirty-five were operated on as long as seven years after injury. Only eight patients had a meniscal tear that was not accompanied by injuries of either the anterior cruciate ligament or the collateral ligaments, or both. At a mean follow-up of eighteen months (range, six to thirty-nine months), forty-two patients (84 per cent) had clinically apparent healing of the sutured meniscal tear. Repeat arthroscopy was done in twenty-seven (64 per cent) of these patients, four to twenty-nine months (mean, twelve months) after the operation. The arthroscopy proved that all of these repaired tears had healed. Eight patients had a second tear after the initial repair: four were reruptures at the sutured area and four were new ruptures in another area of the meniscus and were associated with fresh trauma. All of these patients subsequently had an arthroscopic meniscectomy.

目的探讨外侧半月板后根部(lateral meniscus posterior root,LMPR)修复联合前十字韧带(anterior cruciate ligament,ACL)重建术治疗合并LMPR慢性撕脱损伤的ACL撕裂的临床疗效。方法回顾性分析2015年7月至2017年6月LMPR慢性撕脱合并ACL撕裂患者33例,男30例,女3例;年龄(27.7±7.5)岁(范围17~45岁)。由同一术者施行胫骨隧道拉出式LMPR修复自体腘绳肌腱ACL解剖单束重建术,随访2年以上。根据二次关节镜下探查结果评估半月板愈合,根据Lysholm和Tegner评分评估膝关节主观功能,根据麻醉下KT-1000侧侧差值和轴移试验评估膝关节客观稳定性,根据矢状面MRI上胫骨前移距离评估股骨-胫骨静态位置关系。以术前胫骨前移距离进行分组,前移至少6 mm者(前移阳性组)18例,前移小于6 mm者(前移阴性组)15例,比较术前及术后2年两组患者胫骨前移距离及其降低程度的差异。结果所有患者随访(27.5±4.0)个月(范围24~39个月)。LMPR完全愈合23例(70%)、部分愈合9例(27%)、不愈合1例(3%)。Lysholm评分由(60.4±13.6)分提高至术后1年的(82.7±11.1)分、术后2年的(91.4±9.1)分(F=155.996,P<0.001);Tegner评分由3(2,5)分[M(P25,P75)]提高至术后1年的4(3,5)分、术后2年的6(4,6)分(χ^2=47.791,P<0.001)。KT-1000侧侧差值由(9.1±3.3)mm降低至(2.0±1.7)mm(t=11.197,P<0.001);轴移试验由Ⅰ度10例、Ⅱ度20例、Ⅲ度3例改善至正常30例、Ⅰ度3例(U=5.161,P<0.001)。胫骨前移距离由(5.7±3.9)mm减少至(3.5±3.2)mm(t=3.530,P=0.001)。术后2年,前移阳性组的胫骨前移由(8.7±1.8)mm下降至(5.0±3.3)mm(t=4.765,P<0.001),前移阴性组的胫骨前移与术前比较差异无统计学意义(t=0.400,P=0.695)。前移阳性组胫骨前移下降幅度为(3.7±3.3)mm,大于前移阴性组的(0.3±2.8)mm(t=3.115,P=0.004)。结论胫骨隧道拉出式LMPR修复联合ACL重建术治疗合并LMPR慢性撕脱损伤的ACL撕裂,术后2年半月板愈合率高;膝关节主观功能及客观稳定性提高,能够有效改善术前胫骨前移≥6 mm患者的股骨-胫骨静态位置关系。     

Postoperative change in medial meniscal length in concurrent all-inside meniscus repair with anterior cruciate ligament reconstruction

Purpose

Meniscus repair can restore meniscal function that transfers the axial compressive force to circumferential tensile strain. However, few reports have investigated the relationship between concurrent meniscus repair with acute anterior cruciate ligament (ACL) reconstruction and postoperative meniscal position. This study aimed to evaluate medial meniscal size and clinical results in patients who underwent ACL reconstruction and concomitant all-inside medial meniscus repair.

Methods

Twenty patients underwent ACL reconstruction and concurrent medial meniscus repair of a peripheral longitudinal tear using the FasT-Fix meniscal repair device. Medial tibial plateau length (MTPL) and width (MTPW) were determined by radiographic images. We evaluated the Lysholm score, anteroposterior instability, meniscal healing and magnetic resonance imaging (MRI)-based medial meniscal length (MML) and width (MMW). Correlations between MRI-based meniscal size, radiographic measurement and height were investigated.

Results

All patients showed complete healing of the repaired meniscus in arthroscopic evaluation. However, one patient needed a subsequent meniscus repair during the follow-up period. Lysholm score and anteroposterior instability improved significantly. A better correlation was observed between MMW and MTPW than between MML and MTPL. Concurrent all-inside medial meniscus repair with ACL reconstruction significantly increased MML percentage (%MML) (100 MML/MTPL) but did not affect MMW percentage (%MMW) (100 MMW/MTPW).

Conclusions

Concurrent all-inside medial meniscus repair with ACL reconstruction had satisfactory clinical results. %MML was increased by concurrent medial meniscus repair without affecting %MMW. Our results suggest that medial meniscus repair associated with ACL reconstruction may restore meniscal function by adjusting the anteroposterior length of the torn medial meniscus.
