Reverse rotator interval closure.

We describe a technique for reducing capsular volume arthroscopically by shifting the anterior inferior glenohumeral ligament (AIGHL) and capsule up to the top of the subscapularis. This procedure is performed when laxity exists in the absence of a Bankart lesion. The AIGHL is first released from the capsule. This allows sutures to be placed through the capsule inferiorly so that it can be shifted up superiorly during the repair. The AIGHL and capsule are then released from the underlying subscapularis. Sutures are then passed through the capsule and out of the accessory anterior portal, progressing laterally. A BirdBeak suture passer (Arthrex, Naples, FL) is inserted through the superior edge of the subscapularis and is used to grasp each undersurface strand of suture and pull it through and out of the anterior portal. The sutures are then tied sequentially, effectively shifting the capsule and ligament up in a superior direction.

Kinematics of the posterior cruciate ligament/posterolateral corner-injured knee after reconstruction by single- and double-bundle intra-articular grafts.

BACKGROUND: Single- and double-bundle reconstructions have been proposed for the knee after combined posterior cruciate ligament/posterolateral corner injuries. HYPOTHESIS: The double-bundle posterior cruciate ligament reconstruction is superior to the single-bundle posterior cruciate ligament reconstruction with regard to restoration of normal knee kinematics to the posterior cruciate ligament/posterolateral corner-sectioned knee. STUDY DESIGN: Controlled laboratory study. METHODS: Kinematics of 8 fresh-frozen, cadaveric human knees were determined in the following conditions: intact, sectioned posterior cruciate ligament/posterolateral corner, single anterolateral bundle posterior cruciate reconstruction, and double-bundle posterior cruciate reconstruction. RESULTS: The sectioned knee demonstrated a posterior shift of the tibial neutral position and the abnormal posterior, varus, and external rotation laxities used clinically to define a combined posterior cruciate ligament/posterolateral corner injury. Both reconstructions restored the posterior laxity to levels that were not statistically different from those seen in the intact knee, but the double-bundle reconstruction more closely mimicked the posterior laxity profile of the intact knee, having statistically lower posterior laxities than did the single-bundle reconstruction at 30 degrees, 60 degrees, and 90 degrees of flexion (P < .05, analysis of variance, HSD test). The resting position of the tibia after double-bundle reconstruction trended to be anteriorly subluxated relative to its position for the intact knee at flexion angles of 30 degrees and greater (P <.05, paired t test). Neither technique corrected the abnormal varus or external rotation laxities. CONCLUSION: With either single- or double-bundle reconstructions, additional posterolateral reconstruction is recommended to correct the external rotation laxity. CLINICAL RELEVANCE: Knowledge of the kinematics of the combined posterior cruciate ligament/posterolateral corner-injured knee is important in the proper diagnosis of the injury and in the selection of the appropriate surgical reconstruction.

Arthroscopic capsular plication-shift.

We describe a technique of arthroscopic capsular plication and shift used to address both anterior and posterior capsular laxity. This technique is used when the labrum is intact or if laxity persists after labral repair.

"Smile" incision: an approach for open reduction and internal fixation of calcaneal fractures.

MATERIALS: A consecutive group of 73 patients (77 calcaneal fractures) treated with open reduction and internal fixation through a smile-shaped lateral approach to the hindfoot were reviewed retrospectively. Inclusion criteria were a closed displaced intra-articular fracture of the calcaneus, no compartment syndrome, and adequate followup. Followup ranged from 4 months to 4 years. RESULTS: One patient had a deep wound infection that required removal of hardware and intravenous antibiotics. No deep dehiscence or flap necrosis occurred. Superficial dehiscence occurred in three patients (4%) and superficial necrosis was seen in nine patients (12%); all resolved with continued casting to protect the wound. Six patients (8%) complained of numbness or pain in the sural nerve distribution. No symptomatic neuromas were seen. Reflex sympathetic dystrophy occurred in three patients (4%); all resolved with sympathetic blocks. Only one patient required an additional procedure for treatment of a wound-related problem or infection. CONCLUSION: The "smile" incision provides good fracture exposure for reduction without added morbidity.

Arthroscopic assisted mini-open biceps tenodesis: surgical technique.

We describe a safe and simple approach for performing biceps tenodesis. This is performed in conjunction with arthroscopic inspection and debridement. This approach is less invasive than a deltopectoral approach and has been tested and proven secure.

The Tuckahoe knot: a secure locking slip knot.

We describe a simple and easy-to-tie knot that can slide and lock. The benefit of these characteristics is that when the knot is seated and locked, it is secure in that it will not slip before the 3 reversed half-hitches with alternating posts are placed.

Late reconstruction of chronic distal biceps tendon ruptures with a semitendinosus autograft technique.

We compared 2 groups of patients with chronic distal biceps tendon ruptures, 7 patients treated nonoperatively and 7 undergoing semitendinosus autograft tendon reconstruction. The mean time to surgery after the initial injury was 17 weeks. The mean clinical follow-up in the operative group was 63 months. Functional strength and endurance testing was measured at a mean of 30 months after injury in the nonoperative group and 26 months in the operative group. A 2-incision technique was used. In the allograft reconstruction group, flexion and supination strength was restored to the normal range. The nonoperative group lacked 20% of normal strength. Endurance in both groups was within the normal range. Autograft semitendinosus reconstruction in chronic distal biceps tendon ruptures improves flexion and supination strength when compared with nonoperative treatment. No radial nerve injuries or heterotopic ossification occurred, and all reconstructions remain intact.
