Tendon Pathology

Extensor mechanism injuries are not uncommon in young active individuals. Patellar tendon is a part of extensor mechanism of the knee which is commonly ruptured due to forced eccentric contraction against flexed knee. There have been reports of pathological changes in the patellar tendon which eventually lead to the rupture. The common pathologies include hypoxic tendinopathy, mucoid degeneration, calcific tendinopathy and tendolipomatosis. We report a rare case of ossified proximal patellar tendon rupture in a fit and active skittle player, who sustained indirect injury to knee while playing soccer. The rupture was confirmed on examination and radiographs. We discovered intraoperatively that the ruptured proximal patellar tendon was ossified which was sequentially repaired with two Krackow sutures, JuggerKnot suture anchor and finally augmented with Leeds Keio tape. Postoperatively, a knee brace was used to immobilise in knee extension with progressive increase in range of motion. This report supports the pool of evidence suggestive of patellar tendon pathology in causing ruptures.

<p>Quadriceps tendon rupture is the rarest injury with an incidence of 1.37/1,00,000/year. A patellar fracture is the most common injury associated with extensor mechanism lag, but it is rarely found to have quadriceps rupture rather than patellar tendon rupture. Normally when patella fracture occurs the force is disseminated at the bone level rather than at the muscular level. In this case, the force has disseminated at both muscle and bone leading to fracture of patella and quadriceps tendon rupture. Here we report a case of patellar fracture along with quadriceps tendon rupture.<strong></strong></p>

Achilles Tendon Allograft

Rupture of the patellar tendon must be diagnosed urgently because reconstruction of the extensor mechanism produces better results when it is performed in acute conditions. Reconstruction of chronic extensor mechanism rupture on the contrary is very challenging. Several surgical techniques have been described using a variety of graft choices and fixation methods, but the optimal approach is still under debate. We report our experience of two cases of chronic patellar tendon rupture reconstruction using an Achilles tendon allograft reinforced by a vascularized ipsilateral semitendinosus tendon frame. The rapid functional recovery of the range of motion, only three months postoperatively, showed us that this reconstruction technique was effective.

Rate of extensor mechanism complications after primary and revision knee arthroplasty reaches 12 %. Description and systematization of such complications by literature data is given. Our experience in treatment of 12 patients with such complications after primary knee and in 5 patients after revision knee arthroplasty that made up 1.0 and 13.9% of all interventions, respectively, is presented. Registered complications include para-patellar scars and ossification impingement (4), patellar lateralization (5), patellar dislocation (1), patellar tendon rupture (7). Treatment results in patients after primary arthroplasty are better than after revision intervention - 83.3 and 40% of positive results, respectively. It is shown that high rate (42.9%) of patellar tendon rupture are associated with deep periprosthetic infection. Besides, autoplasty with m. gracilis and m. semitendinosus shows its inefficiency in treatment of such complications.

Knee Extensor Mechanism

Acute rupture of the knee extensor mechanism after patellectomy is extremely rare. We present the case of a patient with acute patellar tendon rupture who had undergone patellectomy 53 years before. Twelve days after the injury, the ruptured patellar tendon was repaired with end-to-end suture. Postoperatively, we splinted the knee for 6 weeks but permitted the patient to walk without limiting weight bearing at 1 week postoperatively. At one-year follow-up, the patient is able to move his knee almost full range of motion and the Lysholm knee score is 81. The patient is satisfied with the outcome. This is the first report to treat acute rupture of the patellar tendon in a patient who had undergone patellectomy. Although careful rehabilitation is required, end-to-end suture might be an adequate surgical procedure for acute rupture of the knee extensor mechanism after patellectomy.

Multiligament Injury

Knee dislocation with concomitant multiligament injury is a rare and devastating injury. We report the successful repair of a rare case of open knee dislocation with concomitant multiligament injury and patellar tendon rupture of an 18-year-old male due to a motorcycle accident. The patient presented with an open wound running parallel to the knee joint line and patellar tendon rupture with full exposure of the cartilage of the distal femur. Staged surgical management including the application of a ring-type external fixator with a hinged joint, lateral collateral ligament repair, medial collateral ligament reconstruction using autogenous hamstring tendon, and joint release was performed. Range of movement was recovered to 0 degrees of knee extension and 80 degrees of knee flexion, and extension lag was negative. The Lysholm score of the patient was recovered to 92. The patient was able to return to work in the construction field 2 years after sustaining the injury. The patient had no complaint of pain and was able to resume construction work, even though reconstruction of the anterior cruciate ligament and posterior cruciate ligament was not performed. The application of a hinged ring-type external fixation device might play a key role in early range of movement restoration and to maintain the reduced position and acceptable recovery of the posterior cruciate ligament injury without the need for reconstructive surgery. This report is the first to describe the safety and effectiveness of staged surgical management for the repair of open knee dislocation with concomitant multiligament injury and patellar tendon rupture. However, further studies with longer follow-up periods will be needed to observe the development of osteoarthritis or weakness of the knee. Staged surgical management is a safe and effective procedure for repairing an open knee dislocation with concomitant multiligament injury and patellar tendon rupture.
