The Thai version of the Kujala score has shown good validity and reliability. This score can be effectively used for evaluating Thai patients with patellofemoral pain syndrome. Implications for Rehabilitation The Kujala score is a self-administered questionnaire for patients with patellofemoral pain syndrome (PFPS). The validity and reliability of the Thai version of Kujala are compatible with other versions (Turkish, Chinese and Persian version). The Thai version of Kujala has been shown to have validity and reliability in Thai PFPS patients and can be used for clinical evaluation and also in the research work.

Background Intra-articular knee injection with steroid or various other agents have been used to control the local inflammation and relieve pain in the osteoarthritis knee. To achieve the maximal potential therapeutic worth and decrease the complications from the inaccurate knee injection, these medications should be delivered directly into the intra-articular space. Injection technique is one of the most important factors for accuracy of knee injection. Therefore, this study was aimed to propose the new modified anterolateral injection technique for higher accuracy of knee injection in symptomatic osteoarthritis knee without effusion. Material and methods Patients with symptomatic osteoarthritis without effusion were included prospectively from May 2014 to May 2015 and randomized into 2 groups for knee injection: Modified anterolateral (MAL), Standard superolateral (SL). Knee injection was performed by one experienced orthopaedic. Accuracy of injection was test by mini air-arthrography technique. The pain from injection were evaluated by visual analog scale (VAS). Result 132 knees were included, 66 knees were modified anterolateral group same as superolateral group. The modified anterolateral injection was significantly yield the higher accuracy rate than the standard superolateral injection (89% vs 58%, P < 0.05). The pain visual analog scale was not significantly different between the modified anterolateral and standard superolateral injection technique (2.61 vs 2.65, P = 0.917) No adverse events were occurred. Conclusion The new modified anterolateral injection yields the higher pooled accuracy rate. From the accuracy and the advantage of the new modified anterolateral injection, this is the preferred injection technique for the symptomatic osteoarthritis without knee effusion.

Purpose and hypothesis: Acromion spur is the extrinsic factor for impingement syndrome and rotator cuff tear. The Rockwood tilt view can be used to evaluate prominence of the anterior acromion, however no study has shown the correlation of findings between the Rockwood tilt view and the arthroscopic finding. Methods: We developed the arthroscopic classification of acromion spur as type 1 flat spur, type 2 bump spur, type 3 heel spur, type 4 keel spur, and type 5 irregular spur. Patients with rotator cuff syndrome who underwent arthroscopic surgery were recruited. Two observers were asked to classify the type of spur from arthroscopic findings and Rockwood tilt views separately in random pattern. The prevalence of supraspinatus tendon tear was also recorded as no tear, partial-thickness tear, and full-thickness tear. Results: The keel spur (33.9%) was the most common finding followed by the heel spur (27.8%). The correlation was high especially for the heel, the keel, and the irregular spur (75.47%, 74.03%, and 72.73%, respectively.) These three types of spurs have a high prevalence of full thickness of supraspinatus tendon tear. Conclusion: The Rockwood tilt view can be used to evaluate the morphology of an acromion spur, especially the at-risk spur that correlates highly with the full-thickness supraspinatus tendon tear. The arthroscopic classification will also be a useful tool to improve communication between the surgeon and the guide for appropriate treatment in a rotator cuff tear patient when encountering the heel, keel, and irregular spur.

Patellofemoral instability is one of the knee problems that can be found in up to 3% of knee injuries, especially in younger aged females. Recent biomechanical studies showed that the main soft tissue stabilizer for patellofemoral stability is the medial patellofemoral ligament (MPFL). More than 200 articles on MPFL reconstruction have been published. Some surgical techniques create multiple holes in the patellar area that may increase the risk of patellar fractures. This technique that we present here attempts to reduce the chance of patella-related complications, while maintaining stability of the reconstructed construct, reducing the use of a lengthy tendon graft within the patella and covering the footprint at the border of the patella closed to the native anatomy of the MPFL.

Acromioclavicular joint osteoarthritis can lead to persistent shoulder pain. Distal clavicle excision is the most common operative procedure in patients with failed, conservative symptomatic acromioclavicular joint osteoarthritis treatment, with some reports of complications. This report describes an alternative procedure that can be used to excise the distal clavicle together with the medial border of the acromion. This technique is a simple procedure because the standard distal clavicle excision can preserve the acromioclavicular ligament, as well as the joint capsule, and achieve an adequate resection length.

Proximal tendinopathy of the long head of the biceps (LHB) is a common shoulder problem that requires surgical intervention, especially in patients with concomitant rotator cuff tears. The comparative results of biceps tenotomy and biceps tenodesis are still doubtful; both techniques show good to excellent results in terms of postoperative pain and functional outcomes. The described techniquedall-arthroscopic LHB transferdis an optional biceps tenodesis technique using all-arthroscopic soft-tissue tenodesis and arthroscopic suturing of the LHB to the short head of the biceps and coracoacromial ligament combined with release of the LHB from the bicipital groove.
