1/127. Three cases of patella fracture in 1,320 anterior cruciate ligament reconstructions with bone-patellar tendon-bone autograft.

    Between September 1992 and December 1996 we reviewed three transverse displaced fractures of the patella occuring in 1,320 ACL reconstructions using bone-patellar tendon-bone autograft. All the patients suffered local injury to the donor knee between 8 and 12 weeks postoperatively. Immediate rigid fixation using single or double anterior tension band allowed early mobilization and full weight bearing. Between 6 and 9 months after fracture, the screws and the wire were removed and the grafts tested. Results of the pivot shift and Lachman test under anesthesia were negative and arthroscopic visualisation showed the graft to be intact. Postoperative assessment included the Lysholm and Tegner scales, the International Knee documentation Committee Evaluation form (IKDC), KT-1000 arthrometer, and isokinetic dynamometer strength testing. No significant differences in the final outcome were noted between reconstructions complicated by patellar fracture and normal ACL reconstructions.

2/127. Extensive post-traumatic ossification of the patellar tendon. A report of two cases.

    Two men, aged 21 and 50 years, were seen with ossification of the patellar tendon after injury to the knee in adolescence. They complained of pain and had patella alta. Large bony masses were excised from below the affected patellae. The patellar tendon was then reconstructed using a Leeds-Keio ligament. The results at six and ten years, respectively, were good, with neither patient having pain or an extension lag.

3/127. A technique for reconstruction of the medial patellofemoral ligament.

    Additional medial patellofemoral ligament reconstruction was performed successfully on six consecutive patients with recurrent dislocation of the patella because of residual patellar instability after medial transfer of the tibial tubercle. A technique for medial patellofemoral ligament reconstruction is described, and complications and postoperative management are discussed. The reconstruction was performed using a double strand hamstring tendon graft in five patients and iliotibial allograft in one. Good stabilization of the patella was achieved in all six patients, resulting in improved confidence in higher levels of activity. The satisfactory outcome of additional medial patellofemoral ligament reconstruction suggests the possibility that the procedure may be part of the optional procedure in proximal realignment for recurrent dislocation of the patella.

4/127. Childhood lipoma arborescens presenting as bilateral suprapatellar masses.

    Synovial lipomatous proliferations are uncommon idiopathic lesions. Suprapatellar synovial plicae commonly are diagnosed with mechanical knee problems. However, it is not widely known that these plicae can isolate the suprapatellar pouch from the rest of the knee joint. We describe a case of complete bilateral compartmentalization of the suprapatellar pouch (plica synovialis suprapatellaris) in which a 10-year-old boy developed articular tumors isolated in this area. Arthroscopic synovectomy specimens revealed the lesions to represent lipoma arborescens. Rheumatologists should be aware of these two findings when examining a child with swollen knee.

5/127. Distal disinsertion of the patellar ligament combined with avulsion fractures at the medial and lateral margins of the patella. A case report and an experimental study.

    A 12-year-old boy presented with a proximally retracted patella 5 months after an injury to the left knee. The clinical and radiographic features and the findings at operation led to the conclusion that the original lesion had been a distal disinsertion of the patellar ligament combined with avulsion fractures at the medial and lateral margins of the patella, produced by the medial and lateral longitudinal patellar retinacula. Loading experiments on amputation and cadaver specimens showed that these retinacula, apart from being tendons for the vastus medialis and the vastus lateralis, respectively, constitute a direct fibrous connection of considerable strength between the patella and the tibia and thus are capable of producing avulsion fractures.

6/127. The locked patella. An unusual complication of haemophilia.

    Mechanical derangements of the knee are an uncommon complication of chronic haemophiliac arthropathy. Two patients with locking of the patella were treated by manipulation. The mechanism of the injury was forced flexion of the knee joint beyond the limit of its restricted range. The injury is a serious one and may take six months to recover.

7/127. patellar ligament reconstruction using allograft patellar ligament: a case report.

    This report describes a method of patellar ligament reconstruction. Our patient sustained a rupture of the patellar ligament and had reconstruction with allograft patellar ligament after failed primary repair. At the 2-year follow-up, his range of motion was 0 degrees to 110 degrees and he was able to return to unrestricted standing work.

8/127. Suture fixation as a treatment for acute traumatic osteochondral lesions.

    This is a report on the treatment of traumatic osteochondral lesions with suture fixation. Equivocal results from traditional, conservative treatment modalities have resulted in a recent surge in research in this area. literature reports of treatments for these lesions often rely on a fibrocartilage healing response that exhibits inadequate weight bearing, lubricating, and durability qualities. We describe here a method by which a large, intact osteochondral fragment over the articulating, weight-bearing portion of the patella may be repaired using suture. This method allows for the preservation of the articular topography without many of the complications seen using other fixation techniques.

9/127. Arthroscopic treatment of infrapatellar tendonitis.

    Infrapatellar tendonitis is a chronic overload lesion in the patellar ligament at the attachment to the lower pole of the patella. This lesion is found primarily in athletes who participate in jumping sports. magnetic resonance imaging or ultrasound can show the extent of tendon pathology. Patellar tendonitis is treated with modification of activities, medications, and therapy. When conservative measures fail, operative debridement has been recommended. Previous reports have described a technique of open debridement of the patellar tendon, followed by an extended period of rehabilitation before returning to sports. Two athletes with persistent infrapatellar tendonitis were treated with an arthroscopic debridement. Both athletes returned to full activities without restrictions within 8 weeks of surgery. Arthroscopic treatment of infrapatellar tendonitis has not been previously described. This technical note describes the technique and two case reports of the arthroscopic treatment of infrapatellar tendonitis.

10/127. rehabilitation program for both knees when the contralateral autogenous patellar tendon graft is used for primary anterior cruciate ligament reconstruction: a case study.

    STUDY DESIGN: Case study of a basketball player who underwent an alternative surgical procedure for anterior (cruciate ligament (ACL) reconstruction and outline of the rehabilitation process designed for this procedure. OBJECTIVES: To describe the surgical procedure, detail the rehabilitation program, and report on this patient's clinical outcome. BACKGROUND: Anterior cruciate ligament injury, its treatment, and rehabilitation continue to be an area of interest to both clinicians and researchers. Surgical procedures have been refined and rehabilitation programs are constantly being evaluated and updated to allow the safest and most predictable return to activity. Currently, the autogenous bone-patellar tendon-bone graft is the graft of choice for ACL reconstruction. Typically the graft is taken from the ipsilateral knee. An alternative procedure is to take the graft from the contralateral, noninvolved knee, allowing 2 separate rehabilitation programs to take place. methods AND MEASURES: The patient was followed from the time of injury to 2 years postoperatively. Data collected included range of motion, isokinetic strength scores, ligament stability scores, subjective evaluation, and functional measures. RESULTS: At 3 weeks postoperative the patient had nearly full range of motion in both knees, normal gait, and was beginning sport-specific drills. He was shooting the basketball and jumping by 5 weeks and returned to competitive sports 6 weeks after surgery. He was able to play in all 32 games of the season, starting in 23 of them. CONCLUSIONS: Using the contralateral patellar tendon graft may be appropriate for primary ACL reconstruction of patients, particularly those desiring an early expedient return to athletic competition.
