Background: Early detection and treatment of extensor mechanism rupture are essential for a long-term functional knee joint. In chronic cases, quadriceps muscle retraction and contracture make surgery difficult and results are less predictable. Objectives: The purpose of this study was to evaluate outcomes in the cases of late repaired patellar tendon ruptures. Methods: This study included patients with chronic patellar tendon rupture who were operated at Shafa orthopedic hospital from 2006 to 2013. Results: A total of ten patients were evaluated, presenting twelve cases of chronic patellar tendon rupture. Patients had a mean age of 34.4 years (range 18 -58). Seven cases were caused by a traffic accident and three by a fall. The mean length of time from injury to surgery was 23 months (range 3 -132). The mean time of follow-up was 6.2 years (range 3 -9). Cerclage wire reinforcements were applied in nine of the knees and the left three knees had fiber wire reinforcement. Tendon graft augmentation was applied in ten of the knees; six with semitendinosus and gracilis autograft, two with semitendinosus autograft, one with an Achilles tendon allograft, and one with a tibialis anterior allograft. Means for preoperative/postoperative active knee range of motion, extension lag, subjective international knee documentation committee score, and modified Cincinnati scores were 81/117, 32/2, 22.7/84.5 and 24/87, respectively. Wire breakage was seen on all nine knees but wires were removed in only two symptomatic cases. Conclusions: Good to excellent results were obtained in terms of functioning with operative treatment of chronic patellar tendon rupture. Direct repair with autogenous or allogenic graft augmentation and cerclage wire reinforcement and postoperative cast immobilization are recommended.

“…Surgical repair of the ruptured patellar tendon can be broadly categorized into primary repair only (7) and primary repair with augmentation (4,8,11,15). When augmentation is performed, free tendon graft using strips of the gracilis tendon and semitendinosus (I 5) tendon may be used; wire cerclage (4,8,11) has also been employed.…”

“…When augmentation is performed, free tendon graft using strips of the gracilis tendon and semitendinosus (I 5) tendon may be used; wire cerclage (4,8,11) has also been employed. Early immobilization in long-leg braces is the most frequent treatment, although Donati et al (4) suggested early mobilization was important for optimal recovery of the athlete.…”

Quadriceps tendon reconstruction using a fascia lata included in a reverse‐flow anterolateral thigh flap

et al. 2019

View full text Add to dashboard Cite

Quadriceps tendon re-rupture after surgical repair is an overall estimated 2% complication. We report a case of reconstruction in a large tendon and soft tissue defect using a reverse-flow anterolateral thigh (ALT) perforator flap including fascia lata in a 75-year-old man presented with septic necrosis of a reconstructed quadriceps tendon. A reverse-flow ALT flap was transferred to the knee defect; the fascia lata was sutured to the residual tendon. Post-operative flap congestion and infection were successfully treated with debridement and conservative treatment. One year after surgery, the patient was able to fully and actively extend the knee, with an acceptable aesthetic appearance. The reverse-flow anterolateral thigh flap including fascia lata may be a good option for coverage of soft-tissue defects around the knee and contemporary quadriceps tendon reconstruction, particularly in case of septic tendon necrosis, where the use of non-vascularised tissues is contraindicated.
