Purpose: This study examines the influence of preoperative fatty infiltration (FI) of the subscapularis tendon (SBS) on outcomes following reverse total shoulder arthroplasty (rTSA) with SBS repair.

Methods: A cohort of 161 rTSA patients with SBS repair, followed for a mean of 45.3 months, was divided into three groups based on FI: Group A (intact upper and lower portions,  = 85), Group B (intact lower portions,  = 44), and Group C (fatty infiltrated in both portions,  = 32).

Background: Arthroscopic rotator cuff repair with biceps rerouting (ABR) has emerged as a reliable option for treating large posterosuperior rotator cuff tears (RCTs). This study aims to compare functional and structural outcomes of early vs. delayed motion rehabilitation protocols following ABR.

Article Synopsis
  • - The study evaluated the effectiveness of acellular human dermal allograft (HDA) augmentation in preventing retears and improving shoulder function in patients with large to massive rotator cuff tears who underwent arthroscopic repair.
  • - Results showed that patients with HDA augmentation experienced significantly better pain relief, shoulder function, range of motion, and satisfaction compared to those without augmentation over an average follow-up of 20 months.
  • - Notably, the retear rate in the HDA group was only 5.6%, compared to 29.1% in the group without augmentation, highlighting the potential benefits of using HDA in surgery.

Background: The irreparable subscapularis (SSc) tears pose an extremely difficult situation to manage, especially in the younger population. The anterior capsular reconstruction (ACR) with human dermal allograft (HDA) is an alternative to tendon transfer with sound biomechanical advantages and clinical outcomes. The purpose of this study was to evaluate the early clinical and radiologic outcomes of open ACR with HDA in patients with irreparable SSc tears.

Arthroscopic superior capsular reconstruction is gaining popularity in managing irreparable rotator cuff tears in younger patients without arthrosis. One of many reasons for the increase in this trend is the simplification of technique using allograft and knotless technology for fixation. Despite all this, turbulence control and suture management are still arduous undertakings.

Background: The main purpose of this study is to assess the compatibility of medial tibial condyle (MTC) morphometry of Indian population with that of six contemporary UKA prostheses tibial components. We hypothesized that from the currently available UKA designs at least one would fit the MTC morphometry optimally as per the manufacturer's recommendation.

Methods: We used CT morphometric data of 100 (66 males and 34 females) consecutive nonarthritic adult knees with reference to the MTC to assess the compatibility of currently available (in India) UKA prostheses.

We present a rare case of femoral head indentation fracture without associated hip dislocation in an elderly female secondary to a low-energy trauma. She was managed with primary total hip arthroplasty and achieved an excellent functional outcome. We have proposed the mechanism of injury and discussed shortcomings in the present classification systems.

Introduction: Alkaptonuria is a rare metabolic disorder of autosomal recessive pattern of inheritance caused due to homogentisic acid oxidase enzyme deficiency. As a result, polymers of homogentisic acid get deposited in excessive amounts in the connective tissues, leading to brownish-black pigmentation termed as ochronosis. As the disease progresses, chronic inflammation results in arthritis of large weight-bearing joints.

Introduction: Myositis ossificans (MO) is a benign ossifying lesion. It is also known as heterotopic ossification of muscle, in which lamellar bone is formed in the muscle most commonly due to trauma or neurological injury. Complete extra-articular ankylosis due to extensive MO is rare.
