Surgical Principles Medial displacement of the medial half or the medial two thirds of the patellar ligament on the proximal tibia; the detached ligament is anchored to a chiselled trough in the bone with a cancellous bone screw and serrated washer. Division of the fibres of the tractus iliotibialis leading into the patella and of the lateral extensor retinaculum up to the vastus medialis (so-called “lateral release”). Transfer of the vastus medialis in lateral and distal direction by approximately 1 to 1.5 cm onto the patella. Double breasting of the medial extensor retinaculum. First published in: Operat. Orthop. Traumatol. 1 (1989), 94–99 (German Edition).  相似文献

Summary Between January 1986 and August 1995, we treated 86 patients suffering from lateral displacement of the patella with arthroscopic medial tightening and lateral release after a conservative functional treatment remained unsuccessful. 49 patients were available for follow-up studies. 29 patients were treated after primary dislocation of the patella, and 20 patients after recurrent dislocations (2–20). The lateral release was performed by arthroscopy in 28 patients and in 21 patients in an open procedure. The mean follow-up time was 47.3 months. The rate of reluxation was 8 %. In the opinion of the patients, 44 (90 % of the follow-up) operations were evaluated as good/very good, the average Lysholm score was 87.3 ± 13.9. The clinical results were influenced by the point of time of the operation. Patients with monoluxation showed a lower rate of reluxation (3 % vs. 15 %) and superior functional and subjective results than those with recurrent dislocation. However, there were no significant differences between the open and closed performed lateral release. We recommend the technique presented here as a minimal-invasive method especially for patients with monoluxation of the patella.   相似文献

Summary: Accurate clinical evaluation of patients with patellofemoral disorders is the cornerstone of effective treatment. This article defines how a careful history and physical examination can direct strategies for nonoperative and operative management. A critical analysis of traditional methods of evaluation and a streamlined rational approach to clincial evaluation is presented. Key questions and important physical findings that affect treatment decisions are emphasized.Arthroscopy: The Journal of Arthroscopic and Related Surgery, Vol 15, No 8 (November), 1999: pp 841–851  相似文献

Purpose: Many methods of realigning the patella have been described. Most techniques for proximal realignment involve an open medial reefing or advancement of the vastus medialis obliquus. Arthroscopically assisted methods have been described, but these all involve the need for a medial incision to tie sutures. This article describes an entirely arthroscopic technique for proximal realignment that eliminates the need for an incision, and reports the 2-year follow-up results using this technique. Type of Study: Retrospective review. Methods: Over a 5-year period, 26 patients (29 knees) with patellar instability were treated with an outpatient arthroscopic all-inside medial reefing and lateral release. Arthroscopic reefing was performed by percutaneous passage of suture followed by arthroscopic retrieval and knot tying inside the joint. Before knot tying, a healing response was initiated along the medial retinaculum by either gentle shaving with a whisker blade or by radiofrequency thermal response. Rehabilitation consisted of 1 week of immobilization followed by an accelerated program of range of motion exercises and vastus medialis obliquus strengthening. Results: At follow-up, 93% of patients reported significant subjective improvement. The average Lysholm score improved from 41.5 to 79.3 (P < .05). Preoperative and postoperative radiographs were measured for congruence angle, lateral patellofemoral angle, and lateral patella displacement, and all showed significant improvement postoperatively (P < .05). There were no complications and no redislocations. Patients reported a significant improvement in pain, swelling, stair climbing, crepitus, and ability to return to sports (P < .05). Conclusions: Arthroscopic patella realignment is a viable technique that offers results comparable or superior to published results for open or arthroscopically assisted realignment.Arthroscopy: The Journal of Arthroscopic and Related Surgery, Vol 17, No 9 (November-December), 2001: pp 940–945  相似文献

Acute lateral dislocation of the patella has been associated with disruption of the medial restraints of the patella. Following non-operative management there is a re-dislocation rate of up to 44%. The purpose of this study was to test whether sonography is a reliable method of assessing the medial retinaculum after acute dislocation of the patella. Ten patients following acute patellar dislocation had an ultrasound scan (USS) performed by an experienced musculoskeletal radiologist. Each patient subsequently had an examination under anaesthetic, arthroscopy, and repair of the ruptured structures. The ultrasound reports were compared to the surgical findings to determine the accuracy of this investigation. USS located deficiencies in the ligamentous attachments to the medial border of the patella and the presence of avulsed bony fragments, all of which were confirmed at operation. The sonographic diagnosis of haematoma or torn fibres in the vastus medialis obliquus (VMO) corresponded with our operative findings. The most significant findings were the correlation of free fluid around the medial collateral ligament (MCL) with avulsion of the femoral attachment of the medial patellofemoral ligament (MPFL) and the presence of avulsed fragments of bone from the medial border of the patella.  相似文献

目的探讨关节镜下射频紧缩与缝合紧缩内侧支持带结合外侧支持带松解术两种方法治疗主要由外侧支持带挛缩紧张、内侧支持结构松驰引起的髌骨外侧半脱位并倾斜的临床疗效。方法对符合选择标准并有完整随访资料的39例(46膝)髌骨外侧半脱位并倾斜患者进行回顾性分析,其中A组17例(19膝):行关节镜下射频紧缩内侧支持带结合外侧支持带松解术;B组22例(27膝):行关节镜下缝合紧缩内侧支持带结合外侧支持带松解术。手术前、术后6月、术后18月分别采用Lysholm膝关节功能评分[1]和Kujala髌股关节功能评分[2]进行功能评估,并测量屈膝30°CT片髌骨倾斜角(PTA)和吻合角(CA)。结果 39例患者均获18~40个月随访(平均26.3个月)。A组术前Lysholm评分、Kujala评分、PTA及CA分别为:(56.38±4.37)、(60.41±5.26)、(4.77°±3.19°)、(6.92°±4.16°);B组术前分别为:(56.45±4.28)、(60.56±4.89)、(4.73°±3.22°)、(6.86°±4.23°);A组术后6个月分别为:(84.56±3.42)、(85.87±3.61)、(13.86°±4.57°)、(-12.15°±4.53°);B组术后6个月分别为:(85.27±3.29)、(86.34±3.85)、(14.21°±4.35°)、(-12.36°±4.41°);A组术后18个月分别为:(78.97±3.74)、(79.52±4.58)、(10.08°±4.42°)、(-7.68°±4.46°);B组术后18个月分别为:(81.64±3.51)、(82.67±4.73)、(13.47°±4.27°)、(-10.82°±4.18°)。两组术后6个月和术后18个月Lysholm评分、Kujala评分、PTA及CA与术前比较差异有统计学意义(A组术后6个月t值分别为:22.136、17.396、7.109、13.515,P〈0.01)、(B组术后6个月t值分别为:27.740、21.524、9.102、16.343,P〈0.01)、(A组术后18个月t值分别为:17.119、11.943、4.246、10.435,P〈0.01)、(B组术后18个月t值分别为:23.647、16.887、8.492、15.448,P〈0.01);两组之间术后6个月Lysholm评分、Kujala评分、PTA及CA比较差异无统计学意义(t值分别为:0.709、0.418、0.263、0.157,P〉0.05);两组之间术后18个月Lysholm评分、Kujala评分、PTA及CA比较差异有统计学意义(t值分别为:2.473、2.253、2.613、2.440,P〈0.05)。结论只要严格按照手术适应证选择合适的患者,关节镜下射频紧缩或缝合紧缩内侧支持带结合外侧支持带松解术两种方法早期均能使髌股关节内外侧软组织重新恢复平衡,有效纠正主要由外侧支持带挛缩紧张、内侧支持结构松驰引起的髌骨外侧半脱位并倾斜,缓解症状,恢复膝关节功能;但中期疗效,缝合紧缩内侧支持带组优于射频紧缩内侧支持带组。  相似文献
