Open wedge high tibial osteotomy has become the trend for correction of varus knee deformities. The drawbacks were the need of autogenous bone graft with its associated morbidity, and later the use of bone substitutes with their cost and delayed healing. In this study, a total of 58 consecutive patients underwent high tibial osteotomy with internal fixation by wedge (toothed) plate and screws without bone graft, from 2004 to 2008. Age of the patients ranged from 24 to 65 years. There were 37 women and 21 men. The osteotomy opening size ranged from 8 to 14 mm. The mean follow-up was 38 months. The osteotomy united in all patients. Average time to union was 12.4 weeks (range 8-16 weeks). Partial loss of correction occurred in one osteotomy. There was significant difference between the healing time and the size of the osteotomy opening. The results at the final follow-up using the HSS score were excellent in 51 knees (88%) and good in seven knees (12%). Despite the routine addition of bone graft as a part of the high tibial osteotomy procedure, this study supports medial opening-wedge high tibial osteotomy up to 14 mm without bone graft or bone substitutes, which shortens the operative time and avoids unnecessary morbidity.

Aim of the work: Translation and validation of three commonly used knee scores to Arabic language: the Lysholm Knee Score (LKS), the Oxford Knee Score (OKS), and IKDC Subjective Knee Form. Methods: Our work focused on translation and validation of the LKS, OKS and IKDC. Construct validity was assessed by comparing the LKS, OKS, and IKDC Subjective Knee Form and previous Arabic translated version of Knee injury and Osteoarthritis Outcome Score (KOOS). Test−retest reliability, internal consistency, and construct validity were assessed, using Intraclass Correlation Coefficient (ICC), Cronbach's alpha, and Pearson correlation coefficient (r). Results: Reliability was excellent for the Arabic IKDC subjective form (0.95), while the Arabic LKS and the Arabic OKS were good: 0.8 and 0.85, respectively. The Cronbach's ά was excellent for the Arabic LKS and Arabic OKS: 0.9 and 0.90, respectively, while the Arabic IKDC subjective form was good (0.89). Construct validity was high for the Arabic LKS and the Arabic OKS: 0.7 and 0.913, respectively, while the Arabic IKDC was moderate (0.4) in cases of ACL and meniscus injuries and mild (0.18) in cases of osteoarthritis. Conclusion: Arabic LKS and Arabic OKS were reliable and valid scores for patients complaining of ligamentous injuries, meniscus injuries, and osteoarthritis to be used for Arabic-speaking people, while the Arabic IKDC had excellent reliability and mild validity in cases of osteoarthritis and moderate validity in cases of ACL and meniscus injuries.

We retrospectively the results in 27 knees (26 patients) with cysts of the lateral meniscus. All patients had a meniscal tear (20 horizontal, 7 transverse) and pain over the lateral joint line with a palpable mass. The pathology was in the middle or anterior one-third of the meniscus. Arthroscopic surgery was performed in 22 knees, consisting of partial excision of meniscal tear, leaving a peripheral rim, coupled with débridement of the cyst; open cystectomy was performed in the remaining 5 knees. Average follow-up was 58 months (range 9-110). All patients but two were satisfied with the results.

Arthroscopic release of ECRB in patients with chronic lateral epicondylitis is a reproducible method with a marked improvement in function within a short period, with special consideration for resection of radio-capitellar capsular complex.

Osteoid osteoma (OO) is the most commonly seen benign bone-forming lesion. It can occur anywhere, including the metaphyseal regions of small and large bones. We present 2 cases that underwent an arthroscopic technique for removal of OO of the femoral neck. The diagnosis was confirmed by computed tomography in addition to magnetic resonance imaging. The lesions were accessed arthroscopically and excised by unroofing and curettage. The clinical and radiographic findings are presented, along with the surgical management. The patients improved dramatically postoperatively. OO of the femoral neck should be included in the differential diagnosis of hip pain in young patients. Arthroscopic excision and curettage provide a good choice for management, with low morbidity and rapid recovery.
