Orthopedics

Conservative treatment had previously been used in our institution to treat the painful stiff knee joint following total knee arthroplasty (TKA). However, the result was not satisfactory. Arthroscopic surgery was then performed in 11 patients with painful knee joints with limited motion who had previously undergone TKA. ⋯ Flexion improved up to 90 degrees in all patients in the early postoperative period following arthroscopy. However, the benefits declined with time. To avoid the potential complications of manipulation and open arthrotomy, arthroscopic surgery is an option for treating the painful stiff knee joint.

The latissimus dorsi often is used as a functional muscle transfer to restore elbow and shoulder motion. Although less common, its use as a pedicled muscle flap with a split-thickness skin graft provides excellent soft-tissue coverage of large upper extremity wounds. Seven male patients ranging in age from 6-71 years were treated with a pedicled latissimus dorsi muscle flap and split-thickness skin graft for coverage of open wounds of the shoulder, arm, or elbow with exposed vital structures (mean wound size: 15x10 cm). ⋯ At mean 16-month follow-up (range: 3-41 months), all muscle flaps had contoured well, producing satisfactory cosmesis. Functional results were good, and all patients were satisfied with their outcome. The tendinous insertion is left intact to guard against excessive traction on the pedicle when the flap is used for soft-tissue coverage only.
