RESUMEN
BACKGROUND: Extensor mechanism disruption following total knee arthroplasty (TKA) is a rare complication and results in significant morbidity and severe functional limitations. Quadriceps tendon rupture in the early postoperative period after TKA is one limitation about which there is a significant paucity of available information. METHODS: In this retrospective study of 2404 patients who underwent primary TKA between June 2015 to May 2016, there were 10 quadriceps tendon ruptures in seven patients (three bilateral, four unilateral) presented within 3 months after surgery. The rupture was due to a sudden fall while walking or getting up from a chair. All seven patients presented with haematoma formation around the knee, inability to get up and inability to walk. Diagnosis was confirmed by ultrasonography and managed by exploration and end-to-end tendon repair by suturing. RESULTS: In our study, incidence of quadriceps tendon tear in the early postoperative period (within 3 months) after TKA is 0.29% (seven of 2404). All patients had rupture within 90days of primary TKA; early primary repair was performed in all cases. All patients achieved preoperative range of motion without extension lag or restriction in range of movement within 6 months of repair of the quadriceps tendon. CONCLUSION: Early identification and prompt treatment of quadriceps tendon injury followed by controlled postoperative rehabilitation results in excellent short-term and mid-term outcomes.

UNLABELLED: Elbow trauma is challenging to manage by virtue of its complex articular structure and capsuloligamentous and musculotendinous arrangements. We included 17 patients with elbow dislocation and associated injuries in this study. The study protocol included early elbow reduction and planned fixation of the medial or lateral condyle, coronoid and radial head. The sample was 73% male and 27% female with mean duration follow-up of 8 months, and mean age of 37 years. The mean Mayo Elbow Performance Score was 96 points at conclusion of follow-up, indicating an excellent result in 14 patients. Whenever the radial head was excised, we performed a strong transosseous ligamentous repair of the medial and lateral collateral ligaments. Fixation of the coronoid is essential for elbow stability. A small avulsed fragment can be fixed using an ACL jig. We found this technique very useful. Early planned intervention, stable fixation, and repair provide sufficient stability and enhance functional outcomes. KEY WORDS: elbow dislocation, ligament instability, coronoid fracture.
RESUMEN
UNLABELLED: Reconstruction of degenerated ruptures of the tendoachilles is a challenge. Ruptured tendons and the remaining tendon ends are abnormal. A number of methods have been described in literature reconstruct the tendoachilles, but with variable results(1). We used peroneus brevis tendon in 20 patients to augment the repair of degenerated tendoachilles tears by creating a dynamic loop as described by Teuffer et al(2). All patients were followed up for atleast 18 months. At the last postoperative visit, 18 out of 20 patients were able to do a toe raise. Eighty-five per cent of patients had excellent or good results and 15% had fair or poor results using modified Rupp scoring. Advantages offered by this procedure are the use of a single incision and mini incision and use of a dispensable tendon such as the peroneus brevis without entirely depending on the damaged tendon for healing. KEY WORDS: Degenerative tear of tendoachilles, augmented repair, peroneus brevis tendon.
