[The therapeutic effect analysis of three kinds of methods for the management of post traumatic knee stiffness].

OBJECTIVES: To investigate the therapeutic effect of rehabilitation, arthroscopy and "hybrid technique" for posttraumatic knee stiffness (PTKS), and to make the best choice for the treatment. METHODS: From February 2004 to November 2009, 66 patients suffered from PTKS were treated, and the clinical data were studied retrospectively, 36 male and 30 female patients with an average age of 41 years were analyzed, knee stiffness time averaged 15 months (0.5 - 108.0 months), 21 cases of patients were treated with rehabilitation (rehabilitation group), 22 cases of patients with arthroscopy + rehabilitation (arthroscopy group) and 23 cases of patients with mini-invasive "hybrid technique" + rehabilitation (hybrid technique group). For each case, the difference of range of motion (ROM) and hospital for special surgery (HSS) score of the knee before and after the treatment were analyzed statistically. The characters of PTKS including the course of the disease, the degree of extensor mechanism involving, physical examination and other ancillary data were also analyzed. The management methods for PTKS were summarized. RESULTS: Total 66 cases were followed up ranging from 24.0-72.5 months and the mean time was 34.2 months. The average ROM was improved obviously: rehabilitation group increased from 45° ± 22° to 95° ± 24° (t = -11.2, P < 0.05), arthroscopy group from 47° ± 26° to 118° ± 11° (t = -11.0, P < 0.05) and hybrid technique group from 36° ± 22° to 110° ± 14° (t = -13.4, P < 0.05). Both ROM and HSS score of the knee before and after the treatment for each group showed significant difference statistically (t = -9.1, -6.0, -5.2, P < 0.05). Wound necrosis, tearing, re-fracture and extension lag were not found. According to Judet standard at final follow-up, 15 cases were excellent, 3 cases good and 3 cases normal in rehabilitation group; 15 cases were excellent, 5 cases good and 2 cases normal in arthroscopy group; 14 cases were excellent, 8 cases good and 1 case bad. CONCLUSIONS: Pathology of PTKS is complex, satisfactory result could be obtained through individualized treatment program, which were established depend on the course of the disease, the degree of extensor mechanism involving, physical examination and ancillary data. The timely and effective surgical interference followed by a comprehensive rehabilitation program is the key point for satisfied outcome.

A less invasive procedure for posttraumatic knee stiffness.

INTRODUCTION: Management of posttraumatic knee stiffness (PTKS) is among the most difficult challenges in postoperative rehabilitation. AIM: The purpose of this retrospective study was to present the outcomes of a procedure for PTKS. In this study, a less invasive procedure was introduced, which included intra-articular arthroscopic release, extra-articular mini-incision release and "multiple Z" lengthening of the knee extensor, as well as an early, aggressive rehabilitation protocol. PATIENTS: A series of patients aged from 29 to 60 years were treated with this procedure from April 2005 to May 2009, and the mean duration of follow-up was 13.5 months. RESULTS: The range of motion increased significantly in all patients. Flexion improved from a mean of 51° preoperation to a mean of 100° at discharge, and the average extension loss improved from 10° to 3° (p < 0.000). The average knee score, according to the Hospital for Special Surgery system, improved from 62 points preoperatively to 77 points at discharge, and 91 points at final follow-up (p < 0.000). All the patients were satisfied with the final ROM gain.

[The treatment of dorsally displaced intra-articular fractures of the distal radius via palmar approach].

OBJECTIVE: To treat dorsally displaced intra-articular fractures of the distal radius, and to assess the integrity of radiocarpal joint and the reliability of stable fixation fracture. METHODS: Sixty-three cases (65 sides) patients with dorsally displaced intra-articular fractures of the distal radius were performed operatively with the open reduction and internal fixation via palmar approach between August 2003 and May 2008. The series included 20 males (21 sides) and 43 females (44 sides). The mean age of patients was 52.4 years ranging from 18 to 82 years. According to the Frykman classification, 6 sides were of type III, 8 of type IV, 5 of type V, 4 of type VI, 13 of type VII and 29 of type VIII. With the exception of the radiocarpal arthrography and the standard antero-posterior and lateral views of the wrist joint, two new tangential antero-posterior and lateral views of the wrist joint were intraoperatively described so as to observe the relation of the distal screws with the articular surface. RESULTS: The 53 cases (54 sides) of the 63 cases (65 sides) were followed up, and the follow-up time was averagely 16.4 months ranging from 4 to 47 months. According to Gartland and Werley criteria, 32 sides were rated as excellent (59.3%), 14 sides as good (25.9%), 7 fair (13.0%) and 1 poor (1.8%), and the excellent-good rate was 85.2%. Observing the new tangential antero-posterior and lateral views of the wrist joint, it showed that screws appeared penetrating into the radiocarpal joint in 26 of the 42 sides by standard antero-posterior view and in 31 of the 42 sides by standard lateral view. CONCLUSION: This palmar approach represents a simple and valuable treatment methodology for the most frequent types of unstable fractures of the distal radius in young and elderly patients.

Management of multijoint stiffness of bilateral upper limbs secondary to heterotopic ossification: case report and literature review.

The management of heterotopic ossification (HO) is controversial. Although some reports have investigated assessment and surgical resection techniques for HO affecting one or more joints, the cases of multijoint stiffness secondary to HO are rare. This article describes a rare case of HO affecting both upper limbs of a 32-year-old man that severely interfered with activities of daily living. We present the rehabilitation management of this case and the functional outcome 1 to 2 yr after excision of the ossific masses.
